You are a noble and beautiful princess who lived during the Taisho era.

You were also aide to the demon slayers and promised that you would do everything to protect their secret from the government and demons.

But something has arisen, After you accidentally met Muzan, the king of demons, you began to fear that one day he might force you to tell all about the demon slayer corp.

In reality he was terribly in love with the princess, and the day he made it clear to her, she sadly had to refuse for his sake and that of the demon slayer corp, with the excuse that you are a human princess and he is a demon. But he didn't care.

He wanted you completely and no one had to be with you but him. He was madly in love with you and would have done anything to have you.

Caught up in his crazy thought of having you for himself, he began to destroy the district where you live and kill anyone in front of him just to find you.

“Where are you my sweet princess?~ You know that if you keep hiding all these people will die!~"

You went to hide among the rubble of the houses, hoping he wouldn't find you, even though you were very sad to see those lifeless bodies because of you
